[dm-devel] bufio & write completion indication

["Kasatkin, Dmitry" <dmitry kasatkin intel com>]

Hi,

I have a question.

How dm target can be sure that data really have been written to storage?

- for remaped request
bio_end really indicates that?
or data can be stuck in block buffers?

- for bufio requests
dm_bufio_write_dirty_buffers() provides that ?


Thanks,
Dmitry
